What will I learn?
This Lenses Course offers a quick and practical way to master geometrical optics for vision correction. You will cover thin-lens basics, sign conventions, ray tracing, and apply them to spectacle design, diopter calculations, vertex distance adjustments, and refractive errors. With clear examples and clinical cases, you will do precise calculations and confidently explain lens choices.
